Secured to the shaft 30 In the drawings Ihave shown the attachadjacent to the gear-wheel 31 are two fixed ment asapplied to that class of adding-macollars 32 and a loose collar Carriedby the loose collar 33 is a short shaft 34. Surrounding this shaft 34 isa hollow shaft or sleeve 35, having secured to its lower end a bevelgear-wheel 36, meshing with the bevel gear-wheel 31, hereinbeforedescribed. Secured to the upper end of the sleeve 35 is an elongatedgear-wheel 37. This gear-wheel 37 meshes with a toothed segment 38,pivoted at 39 to a rearward extension 40 of the top plate 16. Carried bythe segment 38 is a forwardlyprojecting handle or lever 41. This handleor lever travels over a curved scale 42, which is secured to forwardextensions 43 and 44, respectively, of the top plate 16 and correspondsto the keyboard of a key type-writing machine. The lever 41 ispreferably provided with a clip 45, as best shown in Fig. 1, so as tomaintain the lever in contact with the said scale 42.

Surrounding the shaft 30 is a hub 47, provided with a spline or feather48, which engages with alongitudinal groove in the said shaft 30, so asto allow the hub to move longitudinally of the shaft, but to beincapable of rotation independently thereof. Carried by the hub 47 is atype-wheel 49, provided with characters corresponding to the characterson the scale 42. Secured to the type-wheel 49 is a star-wheel 50.Surrounding the hub 47 are two end plates 51 and 52, which, togetherwith a connecting top'plate 53, form a .carriage for controlling themovement of the type-wheel 49. Secured to the top plate 53 by means ofscrews 54, Fig. 4, are two blocks 55, provided with dovetailed openingsfor receiving the beveled cross-bar 27. The blocks 55 are connected by afront plate 56, preferably formed integral therewith. Carried by the endplate 51 are a pair of ink-rolls 57 for inking the type-wheel 49.Carried by lugs 59 on the end plate 52 is a rock-shaft 60.

This rock-shaft 60 has secured to it a lockingarm 61, having a beveledupper edge adapted to engage with the teeth of the star-wheel 50, andthus retain the printing-wheel in alinement while printing. Therock-shaft 60 also has secured to it a bent arm 62, which passes upthrough an opening 63 in the top plate 53 and thence down through asecond opening 64 in said plate and terminates directly above therack-bar 18. Pivoted to the front plate 56 is a feed-dog 65, whichengages with the teeth of the rack-bar 18 to feed the typewheel alongthe shaft 30. 66 is a pin carried by the plate 56 for locking thefeed-dog when the carriage is in its depressed position. 67 is a pincarried by the dog 65 and adapted to be engaged by a finger-lever 68 toraise the dog out of engagement with the rack when it is desired to movethe carriage toward the left. 69 and 7 0 are pins for limiting themovement of the finger-lever 68.

Pivoted to the end plate 25 is a key-bar 71, which passes up through anopening 72, Fig. 5, in the top plate 16. This bar 71 has secured to itsupper end a key 73 for use in printing the various characters carriedupon the type-wheel 49. Pivoted to this bar 71 is a short key-lever 74,carrying a key 75. This lever 74 is provided with a locking-finger 76,and it is held in its normal position by means of a small coil-spring77. The opening 7 2 in the frame 16 is of such width as to allow thelocking -finger 76 to pass down through it when the key-lever 74 is inits normal position. When, however, the bar 71 is depressed by means ofthe key 75, this finger 76 will be projected beyond the bar, so as tocome in contact with the top plate 16, and thus limit the movement ofthe bar and prevent the wheel 49 from coming in contact with the platento print.

In Fig. 8 I have shown one form of adding mechanism with which mytype-writing attachment is adapted to cooperate. Inasmuch, however, asthe particular form of adding mechanism is immaterial, and I do notclaim the same except in combination with my typewriting device, thesame will be only briefly described. The cross-bar 11, hereinbeforereferred to, is carried by brackets 80, secured to the casing 10 of theadding-machine, and preferably to the base or lower portion thereof. 81represents the keys of the addingmachine, which are depressed toset-stops 82. These stops in turn limit the movement of a toothed sector83, which cooperates with adding-wheels 84 to accumulate the sumthereon. At the same time a second toothed sector 85 cooperates withprintingwheels 86 to position the same to print upon the printing rolleror platen 12. 87 is an inking-ribbon which is interposed between thetype-wheels 86 and the platen 12 to enable said type-wheels to printupon the paper carried upon said platen. The type-sectors 83 and 85 alsoserve to transfer the sum or total back from the addingwheels 84 to thetype-wheels 86, so that the said type wheels may cooperate with theplaten to print the sum or total as well as the individual numbers.

The operation of my attachment is as follows: In the normal operation ofthe addingmachine the platen 12 is in the position shown in dotted linesin Fig. 1 and the characters will be printed along the center line ofthe side of the said roll or platen. In this position the platen 12 doesnot cooperate with the type-writing mechanism, but is adapted to beacted upon only by the printing device of the adding-machine. When theroll or platen is swung laterally up into the position shown in fulllines, this line of printing will be brought into a visible or sightposition and directly beneath the type-wheel 49. When in thisposition,it is evident that the platen 12 is adapted to cooperate onlywith the type-writing mechanism and cannot be acted upon by the printingmechanism of the adding-machine. The lever or handle 41 is now movedalong the IIO mp4s

scale until the edge of the lever indicates the character it is desiredto print. The movement of this lever will be communicated, by means ofthe toothed segment 38, to the elongated gear-wheel 37. This wheel, bymeans of the bevel gear-wheels 31 and 36, will impart the movement tothe shaft 30, which will rotate the type-wheel 19, so as to bring thedesired type directly above the roll or platen 12. The finger-key 73 isnow forced down. This causes the sliding rack to descend, carrying withit the carriage and printing-wheel. As soon as the end of the bent lever62 comes in contact with the top of the rack-bar 18 it will force thelocking-detent 61 up into the teeth of the star-wheel, thus insuring aperfeet alinement of the type-wheel. At the same time the feed-dog 65 byits engagement with the rack-bar 18 will feed the carriage toward theright one space. hen, however, it is desired to feed the carriageforward one space without printing, the key-bar 71 is depressed by meansof the linger-key 75. The spring 77 will allow the bar 74 to swing onits pivot, and thus project the locking-finger 76 to the rear of thebar. This locking-finger will now come in contact with the top plate 16and limit the movement of the keybar 71, so that the type-wheel will notbe brought in contact with the platen, but the carriage will bedepressed sufficiently to cause the feeding mechanism to operate to feedthe carriage one space to the right.
